Arizona Engine Rebuilding

I took my truck there for a engine rebuild. I had high miles but the engine had no leaks or anything wrong with it except I noticed it was loosing a little power when towing so I decided to get a engine rebuild. 2.5 years later and taking it back 14 times for engine oil leaks, exhaust leaks, coolant leaks and my AC didn't work when I picked it up. When I asked them to fix my AC all we did was get in a big argument. I paid $800 to fix it somewhere else. I took it back a number of times for exhaust leaks, when I would pick up the truck it sounded fine but before I got home every time the exhaust leak would come back. I took it to another shop which cost me another $220. They said Master Engine used silicone on the exhaust manifolds and stripped the bolts. My truck started having a knocking noise sometimes when I would pick it up at there shop, the owner told me it should quite in a few minutes. My truck still has oil and coolant leaks. My truck does not have any more power than it did with over 2ooK miles. DON'T waste your money on this place. Please don't waste your money on this place.

I had them do a complete rebuild for 3000 after only 12 months my motor blew a head gasket when I took the car back to them to see if they would honor the 3 year warranty I was told that there under new ownership and that they would not honor the warranty. Want to get revenge please help
